Frameshift Mutation
A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three. "Divisible by three" is important because the cell reads a gene in groups of three bases.
Thanks!
What is one reason why many mutations may be deleterious?.
Answer:
Mutations could affect our bodies and harm them badly. For instance, cancer is a form of cells mutating which harms the body. This could be fatal, because if the cells are mutated, they now gain new functions that they are not supposed to do, which causes the other cells to attempt fighting back.

In general, what is the major difference in outcome when a plant cell and an animal cell are placed in hypotonic solutions.
Answer:
As a result, it also has a higher concentration of water than the cell does. Osmosis draws water out of the solution and into the cells. As a result, plant and animal cells both appear more plump when placed in a hypotonic solution. When viewed under a microscope, the vacuoles of plant cells appear noticeably larger.
2. List and describe two characteristics that distinguish primates from other mammals.
The two characteristics that distinguish primates from mammals are specialized behavior and unspecialized structure.
Primates are characterized by opposable thumbs, forward-facing eyes, and a low sense of smell. Primates have opposable thumbs because they adapted to tree living. All common ancestors of primates have opposable thumbs.
Primates have larger brains (in proportion to their body weight) than other mammals. They also rely more on visual perception at the cost of olfactory perception (which is the primary sense of smell in most mammals).
These characteristics are more prominent in monkeys, and much less so in Loris and Lemurs.

The percentage of probability that their children will have brown eyes is 25%.
Explanation:
In the space provided, explain the adaptations of the plant or animal for surviving in a water
environment.
The plants living in water is also called as hydrophytes or macrophytes. The adaptations of aquatic plants are floating plants and dissected leaves. The adaptations of aquatic animals are respiration through gills, locomotion through fins and tail, and streamlined body for better swimming.
And as for aquatic animals, some of the adaptations of aquatic animals are: Their body is streamlined and hence, they can swim easily. They have gills as the respiratory organs. They have fins as the locomotory organs, Various types of fins are present in fishes such as dorsal fins, pectoral fins, caudal fins etc.

Answer:
Explanation:
By theta mode of replication, an E Coli can replicate its genome in 40 minutes. But the cell division takes 20 minutes. Let us just remind ourselves how an E coli replicates its DNA. The replication always begins at the origin of replication.
PLEASE HURRY!! Mendel decided to use pea plants to study for all EXCEPT which of the following reasons?
A. Pea plants grow slowly and have very few offspring
B. Pea plants reproduce $exually because they have male and female parts.
C. Peas plants have several contrasting characteristics, like height, color, and pea pod shape.
Mendel gave the principles of inheritance and used pea plants for his experiment. Pea plants grow slowly and have very few offspring is not the reason for choosing them for the experiment. Thus, option A is correct.
What is the use of the pea plant in genetics?Mendel used the pea plant for experiments of genetics to show the passing of the traits and characters. He used pea plants as they reproduced sexually and had male and female parts.
They also had contrasting characteristics like the color, height and shape of the pea pods, etc. Also, the pea plant reproduced easily with many offsprings.
Therefore, pea plants grow slowly and have very few offspring is not the correct reason.

Organic Analysis Discussion
Your day in the Forensic Lab had been fairly routine. Around 1:00pm, an investigator drops off some items of evidence to be analyzed from the scene of a homicide. One is a brown gummy substance found at the crime scene, another is an ink pen and note with writing, and the final is an unknown white powder. With each question, your substantial post should have at minimum 5 to 6 sentences for each question and for each of the different pieces of evidence.
For each item of evidence discuss the following:
1) Which analytical method/equipment would you use?
2) Why would you use this particular method for that piece of evidence?
3) How does that method/equipment work? Give details about how the method works.
PLEASE HELP ME
Answer:
1) The brown gummy would be going through a Food & Beverage. The ink pen and note would be going through Chromatography. The white powder would be going through Qualitative analysis.
2) The gummy would be tested for food safety, nutrition, and quality. The ink pen would be tested for separating a mixture of chemical substances into its individual components. The white powder would be tested for a reaction.
3) The method would work for the brown gummy to see why it's brown, how long has it been sitting out, and is there any connection to the case. The method would work for the ink pen and note so it can be thoroughly analyzed to see if it was written in a distressing or frightening matter. The method for white powder would work to determine if it's narcotics or just baking powder.
Explanation:
define tricuspid valve
Answer:
The function of the tricuspid valve is to prevent backflow of blood from the right ventricle to the right atrium.
Explanation:
The tricuspid valve is located between the right atrium and right ventricle of the heart. It is usually made up of three flaps, called the anterior posterior and septal leaflets. The function of the tricuspid valve is to prevent backflow of blood from the right ventricle to the right atrium.
Hope that helps :)
Closure of the tricuspid valve:____.
I. Would prevent blood from flowing into the pulmonary trunk.
II. Contributes to the first heart sound (lub).
III. Occurs at the beginning of isovolumetric contraction of the ventricle.
IV. Occurs immediately before the left atrium contracts.
Answer:
The first heart sound (S1) represents closure of the atrioventricular (mitral and tricuspid) valves as the ventricular pressures exceed atrial pressures at the beginning of systole (point a). S1 is normally a single sound because mitral and tricuspid valve closure occurs almost simultaneously.

what is solid liquid gas
Answer:
A solid has a definite shape and volume. A liquid has a definite volume, but takes the shape of its container. A gas lacks either a defined shape or volume.
Answer:
Solid, gas and liquid is three of the four fundamental states of matter ( the forth one being plasma)
Explanation:
The molecules in a solid are closely together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire available volume like a gas. Liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure, and is the only state with a definite volume but no fixed shape.A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture, such as air, contains a variety of pure gases. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colorless gas invisible to the human observer.

Acid rain has worn away some features on this statue. What type of weathering is this?
erosion
mechanical/physical weathering
deposition
chemical weathering
Help please
This type of weathering is called chemical weathering.
What is chemical weathering?Chemical weathering is a type of weathering that occurs when chemical reactions break down and alter the structure of rocks and minerals. This can happen through processes such as oxidation, hydrolysis, and acid-base reactions.
Chemical weathering can be caused by various factors, including water, air, and temperature. For example, when rainwater containing carbon dioxide dissolves in the soil, it forms carbonic acid, which can chemically break down rocks. Chemical weathering can also lead to soil formation and the release of nutrients that are important for plant growth. Over time, this process can change the appearance and composition of the landscape, affecting not only the geology but also the ecology of the area.

What are the connections between Photosynthesis and Cellular Respiration?
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP.
Extra stuff if you need it: The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Cellular respiration and photosynthesis are direct opposite reactions. Energy from the sun enters a plant and is converted into glucose during photosynthesis. Some of the energy is used to make ATP in the mitochondria during cellular respiration, and some is lost to the environment as heat.
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration. We breathe in that oxygen, which is carried through our blood to all our cells. In our cells, oxygen allows cellular respiration to proceed. Cellular respiration works best in the presence of oxygen. Without oxygen, much less ATP would be produced.
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.
